INDIANAPOLIS – Colts general manager Ryan Grigson isn't changing his offseason plan — even though team owner Jim Irsay won't be around to approve big pay outs or help with the draft preparation.

The Colts owner entered a treatment facility this week after being arrested on preliminary charges of misdemeanor driving while intoxicated and four felony counts of possession of a controlled substance.

Police say they found multiple prescription drugs in his vehicle during a traffic stop. If charged and convicted, Irsay could face six months to three years in prison on each count. He also could be subjected to NFL punishment.

On Friday, Grigson says he hopes Irsay makes a full recovery but that his absence wouldn't change the way Indy prepares for the May draft or deals with potential free-agent signings.
